Yesterday I was in one of our chain pet shops picking up an extra dome lamp so I don't have to switch basking bulbs from day to night, was tired of burning hands lol. Anyway, one of the employees asked if I needed help, you know how that goes, and we got on the topic of uvb. I told him I was using a 4 foot reptisun 10.0 and he told me they were no good and I should swap over to a 150 exoterra cfl coil bulb in a normal lamp. He said it would focus the uvb and provide better absorbtion. I did not go off his advice as everything I have seen here says the 10.0 is the way to go. Opinions?
